Project – the aim you’ll have
You will join an internal OpenStack team that designs, deploys and operates private and sovereign cloud platforms for enterprise clients in Western Europe, including a Benelux managed service provider exiting VMware. Environments range from multi region platforms across several data centres to compact telco and edge clusters. Key selling points: you own the architecture, the same team operates the platform afterwards, and you cooperate directly with client architects.
Role – how you’ll contribute
- Own the platform architecture across control plane, compute, storage and network, including the high availability model and resource sizing.
- Produce the design documentation: High Level Design, Low Level Design, as built documentation and operational runbooks.
- Deploy and upgrade the platform with Kolla-Ansible, with configuration maintained as code in Git.
- Integrate storage, networking, identity and load balancing: Cinder, OVN and Open vSwitch, Keystone with OIDC federation, Octavia and Barbican.
- Set up metrics and logging, and integrate the platform with the client ServiceNow CMDB.
- Run technical workshops, design reviews and acceptance testing with client representatives.
- Act as third line escalation for platforms under management and lead root cause analysis.
- Support pre sales as technical expert and provide technical guidance to engineers in the team.
Expectations – the experience you need
- At least 6 years in infrastructure, virtualisation or cloud platforms, including 3 years with OpenStack in production.
- Experience designing OpenStack architecture, with at least one full implementation from design to production handover.
- Strong command of the core services: Nova, Neutron, Keystone, Glance, Cinder, Placement and Horizon, plus Octavia and Barbican.
- Deployment and upgrade experience with Kolla-Ansible, including playbook customisation and containerised service lifecycle.
- Advanced Linux administration, KVM and libvirt virtualisation, and container runtimes such as Docker.
- Troubleshooting experience across MariaDB or Galera, RabbitMQ, HAProxy, Keepalived, Redis and Memcached.
- Solid cloud networking background: OVN and Open vSwitch, GENEVE or VXLAN overlays, VLAN provider networks, NAT and floating IP addresses.
- English at C1 level, sufficient to run technical workshops and design reviews with client architects independently.
Additional skills – the edge you have
- VMware exit and migration programmes towards OpenStack, including migration tooling and wave planning.
- Enterprise storage integration through Cinder drivers, for example NetApp ONTAP over NFS, or Ceph.
- Telco workloads on OpenStack: SR-IOV, DPDK, CPU pinning, huge pages and NUMA aware scheduling.
- Terraform or OpenTofu, Kubernetes on OpenStack, GPU enabled compute nodes.
- ServiceNow, in particular ITOM Discovery and the CMDB model, or experience in an ITIL based service model.
- Familiarity with sovereign cloud regulatory requirements in the public sector and financial services.
